DuPont™ Elastomers solve pharmaceutical industry seal challenge with unique D-ring seal

Manufacturing companies in the pharmaceutical, biotechnology and food processing industries use hotter and more aggressive cleaning chemicals to sterilize process tubing. In these harsh conditions, perfluoroelastomer O-ring parts exhibit thermal expansion and intrude into the process stream leading to contamination.

DuPont™ Elastomers has developed a special custom 'D' section O-ring design that exhibits virtually no deformation, even after 22 extensive steam-in-place test cycles at 180°C. Some have now been in place for over 18 months without failure, intrusion into the process streams, or contamination... (more)

GE switches to Kalrez® perfluoroelastomer parts to reduce downtime and maintenance costs

GE Power Protection of Gent, Belgium, a division of GE Consumer and Industrial, has dramatically reduced downtime, enhanced the reliability of its key compression molding processes and cut seal costs by at least €21 000 per year by switching to DuPont™ Performance Elastomers (DPE) Kalrez® Spectrum™ 6375 perfluoroelastomer parts. The same Kalrez® O-rings are still functioning well since installation in 2005... (more)
